This Paper Battery is Powered by Bacteria in Your Spit


    Wouldn’t it be great to power your things using only your spit? According to recent news, we may be headed in that direction!

    Researchers at Binghamton University have created a battery with a paper base unlike any other. Just one small drop of saliva will activate it and can generate power for about 20 minutes. Though it is just enough power to get a light going could you imagine what this could bring forth in the future?

    There has been a paper published on this battery in the Journal of Advanced Materials Technology. This battery uses specialized bacterial cells known as exoelectrogens that have the ability to harvest electrons externally, on the outside of the electrode. According to professor Seokheun Choi, a from the Binghamton University and coauthor of this study when it comes to long term storage cells can be freeze dried until used.

    This battery could even be used in challenging places like the desert. Saliva serves two purposes when it comes to this battery: it wakes the frozen cells and provides them with food. Within minutes of spitting on it, the battery will begin pumping out electricity.

    Choi says:

    “This is all about a disposable, easy-to-use, and portable bio-battery that can generate power from bacterial metabolism,”

    “This battery is ready to operate with human body fluids like saliva for on-demand power generation for other disposable low-power applications such as biosensors.”

    This is something that all began with the intention of making origami paper shape itself. Isn’t that amazing? One small idea led to something so monumental! This battery could do so much for this world.

    It could be used to power things like medical devices and HIV tests in places where conventional batteries are too expensive in the future.

    This battery is only made of a few different things so it can be manufactured fairly cheaply and disposed of with ease. This battery is also much less harsh on the environment when looked at beside conventional batteries. For more information on this amazing creation check out the video below.
